Answer 1

My working with time difference for calculating each value separately

var start = new Date('Mon Jul 30 2018 19:35:35 GMT+0500');
var end = new Date('Mon Jul 30 2018 21:15:00 GMT+0500');

var hrs = end.getHours() - start.getHours();
var min = end.getMinutes() - start.getMinutes(); 
var sec = end.getSeconds() - start.getSeconds();  

var hour_carry = 0;
var minutes_carry = 0;
if(min < 0){
       min += 60;
       hour_carry += 1;
   }
hrs = hrs - hour_carry;
if(sec < 0){
       sec += 60;
       minutes_carry += 1;
   }

min = min - minutes_carry;

console.log("hrs",hrs);
console.log("min",min);
console.log("sec",sec);
console.log(hrs + "hrs " + min +"min " + sec + "sec");
